template<class T>

glpp::core::object::attribute_properties class

OpenGL type trait helper.

The attribute_properties type trait can be used to determine OpenGL related attributes of native types. Glpp ships the with overloads for the following types:

• scalar types
  • GLfloat, float
  • GLdouble, double
  • GLint, std::int32_t
  • GLuint, std::uint32_t
  • GLshort, std::int16_t
  • GLushort, std::uint16_t
  • GLbyte, std::int8_t
  • GLubyte, std::uint8_t
• vector types with value_type matching a scalar type
  • glm::tvec2
  • glm::tvec3
  • glm::tvec4

Glpp attribute_properties can be extended for use with custom types, by providing an partial or full template specialisation of attribute_properties implementing the following interface:

template <T>
struct attribute_properties {
    typedef value_type; // equal to T for scalar types and base type for vector types
    static constexpr GLenum type; // The GLenum value corresponding to value_type
    static constexpr size_t elements_per_vertex; // equal to 1 for scalar types or the number of vector elements
};
